A. Application
The optical composite image level is idely used in measuring the gradients of flat surface and cylindrical surface to horizontal direction, the planeness and straightness of slideway or base of machine tool or optical mechanical instrument as well as the correctness of installing position of equipment
B. Technical data
a. each graduation value: 0.01mm/m
b. max measuring range: 0～10mm/m
c.allowance:
1mm/within one meter 0.01mm/m
Within full measuring range 0.02mm/m
d. plane deviation on working surface: 0.0003mm/m
e. each graduation value of the spirit level: 0.1mm/m
f. working surface (LxW): 165×48mm
g. net weight of the instrument: 2kgs.
C. Structure of the instrument
The composite image level mainly consists of the following parts such as microadjusting screw, nut, graduated disc, spirit level, prism, magnifying glass, lever as well as base with plain and v working surface.
